Abstract
Flaxleaf fleabane (Conyza bonariensis(L.) Cronquist) has been considered a major weed in dryland cropping systems in Australia. Resistance in populations of C. bonariensis to glyphosate has also been confirmed. The weed is very difficult to control with any single herbicide application especially when herbicides are applied after the bolting stage. Anecdotal evidence suggests that some chemicals might affect fleabane seed viability and/or dormancy based on the observations that seeds collected from certain paddocks did not germinate. Glasshouse experiments were conducted to investigate whether applications of glyphosate and paraquat could sterilise the weedseeds and affect seed dormancy of fleabane. Results showed that both herbicides affected the seed viability and dormancy, depending on the application timingand the herbicide. The herbicide-induced dormancy decreased during storage under laboratory conditions.

| Other | In 2016, the Council of Australasian Weed Societies (CAWS), along with local hosts the Weeds Society of Western Australia, are celebrating the 20th Australasian Weeds Conference. The biennial conference is being held at the Pan Pacific in Perth, Western Australia which has traditionally been one of the highest attended AWC's, and over 300 delegates are expected from across Australasia. Delegates will come together to meet-up with peers, engage with industry sponsors, and to listen and participate in presentations and field trips on a variety of topics including: Herbicide Resistance Weeds of National Significance Agricultural weeds Environmental weeds Biological control of weeds Modelling and new technologies to manage weeds Legislation, regulation and policy to manage weed |
